Answer 1

Try using DateTime.UtcNow to calculate your timeout period instead of datetime.Now . You may be running into the issue described below:

absoluteExpiration Type: System.DateTime The time at which the inserted object expires and is removed from the cache. To avoid possible issues with local time such as changes from standard time to daylight saving time, use UtcNow rather than Now for this parameter value. If you are using absolute expiration, the slidingExpiration parameter must be NoSlidingExpiration.
